I love my Colossus too. Think it's been about three years now with this case. Close to it anyway.

Why did I choose to put my PSU that way? What if stuff leaks? I have complete confidence in my own work and components selection so that it won't. So it doesn't. I tighten my fittings correctly. Therefore, they don't piss onto components.

I'm not talking about faith either. I built it the best I can, so I know it's not going to f#ck up. Been that way ever since I've watercooled and never yet a problem.
